The DSC button does not disable the X-Drive system components, it simply makes them less aggressive. BMW has a nice (IMO) habit of providing buttons in their rides that change existing functionality. Anyone who has hit the SPORT button in a E46M3 knows what I mean.

I just hope BMW takes a page from Audi on how to design AWD systems....Audi is unstoppable.
